Why does ice from Plano and Frisco homes sometimes look cloudy?
Cloudy ice usually comes from dissolved minerals and trapped air in the water freezing from the outside in, trapping impurities toward the center as it does — the harder the water, the more pronounced this effect. It's cosmetic, not a safety issue, but it's also a visible sign of exactly the mineral content that causes mechanical problems elsewhere in the ice maker.
What mechanical problems does hard water actually cause?
Scale buildup inside the water inlet valve is the big one — it keeps the valve from opening and closing fully, which shows up as slow ice production or an ice maker that stops filling partway through a cycle. Scale can also build up inside the fill tube itself, gradually restricting flow even before the valve fully fails.
Does ice taste bad because of hard water too?
Sometimes, yes — if a refrigerator water filter is overdue for replacement, minerals and trace sediment can affect both taste and clarity. This is a separate issue from the mechanical valve problems but often gets blamed together, since both stem from the same regional water hardness.
What actually helps long-term?
Replace the water filter every 4-6 months rather than stretching it to a year, since harder water clogs filters faster than average. If you're already seeing valve-related slow ice or partial fills, that's a sign the filter alone isn't catching enough — the valve itself likely needs inspection or replacement.
